Drill Bits TRIZ Cases
- Rotary Drill Bit With Gravity-Actuated Folding Jacket
A rotary drill bit uses a gravity-actuated folding jacket to separate from the cylinder body for automatic slag discharge.
- Casing Bit Hollow Crown Segmented Blades Drill-Out
Segmented hollow casing bit crown reduces drill-out volume and damage to subsequent bits.
- Drill Bit Matrix Bodies with Dual Carbide Regions
A drill bit body uses dual matrix regions to tailor wear resistance and toughness across specific blade zones.
- Soil Mixing Blades for Uniform Suspension in Boreholes
Radial mixing blades crush soil and mix it with liquid to form a suspension drawn through blade openings, resolving inefficient space utilization.
- Polycrystalline Diamond Grain Mixture for Graphite-Free Bonding
Bimodal diamond grain mixture eliminates trapped graphite at boundaries, improving structural uniformity and wear resistance.
